   - This helps prevent mistakes such as `if (a & 1 == 0)`
  * White space is free, so use it freely
   - "freely" as in "plentifully", not "arbitrarily"
+ * All `case` statements inside a `switch` need an extra indent.
  * Each and every control statement deserves its braces. This helps maintainability later on when the file is edited, lines added or removed - the control logic doesn't break so easily.
   - The only exception: a `switch` statement with all `case` statements being a single short statement is allowed to use the short brace-less form.
+  - These two rules really mean that indent is governed by braces
  * Add an empty last line in all source files (GCC and GIT can complain otherwise)
  * Use doxy-comments for functions in the header file, format as `/** Description */`
  * Use spaces after the comment markers: `// Comment` instead of `//Comment`

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+		<h1>Setting up the ZeroBrane Studio IDE</h1>
+		<p>
+		This article will explain how to set up ZeroBrane Studio, an IDE for writing Lua code, so that you can develop MCServer plugins with the comfort of an IDE.</p>
+
+		<h2><img src="Static/zbs_logo.png" /> About ZeroBrane Studio</h2>
+		
+		<p>To quickly introduce ZeroBrane Studio, it is an IDE for writing Lua code. It has the basic features expected of an IDE - it allows you to manage groups of files as a project, you can edit multiple files in a tabbed editor, the code is syntax-highlighted. Code completion, symbol browsing, and more. It also features a Lua debugger that allows you to debug your Lua code within any application that uses Lua and can load Lua packages. It is written using the multiplatform WxWidgets toolkit, and runs on multiple platforms, including Windows, Linux and MacOS.</p>
+		<p>Here's a screenshot of a default ZBS window with the debugger stepping through the code (scaled down):<br />
+		<img src="Static/zbs_workspace.png" /></p>
+		<p>As you can see, you can set breakpoints in the code, inspect variables' values, view the Lua call-stacks.</p>
+		<p>ZBS is open-source, the sources are on GitHub: <a href="https://github.com/pkulchenko/ZeroBraneStudio">https://github.com/pkulchenko/ZeroBraneStudio</a>. The project's homepage is at <a href="http://studio.zerobrane.com/">http://studio.zerobrane.com/</a>.
+		
+		<h2><img src="Static/zbs_logo.png" /> First-time setup</h2>
+		<p>Since ZBS is a universal Lua IDE, you need to first set it up so that it is ready for MCS plugin development. For that, you need to download one file, <a href="https://raw.githubusercontent.com/pkulchenko/ZeroBranePackage/master/mcserver.lua">mcserver.lua</a> from the <a href="https://github.com/pkulchenko/ZeroBranePackage">ZBS's plugin repository</a>. Place that file in the "packages" folder inside your ZBS's folder. Note that there are other useful plugins in the repository and you may want to have a look there later on to further customize your ZBS. To install them, simply save them into the same folder.</p>
+		<p>Next you should install the code-completion support specific for MCServer. You should repeat this step from time to time, because the API evolves in time so new functions and classes are added to it quite often. You should have an APIDump plugin in your MCServer installation. Enable the APIDump plugin in the server settings, it's very cheap to keep it enabled and it doesn't cost any performance during normal gameplay. To generate the code-completion support file, enter the <code style="background: #ddd; border: 1px solid #aaa">api</code> command into the server console. This will create a new file, "mcserver_api.lua", next to the MCS executable. Move that file into the "api/lua" subfolder inside your ZBS's folder.</p>
+		<p>After you download the mcserver.lua file and install the completion support, you need to restart ZBS in order for the plugin to load. If there are no errors, you should see two new items in the Project -> Lua Interpreter submenu: "MCServer - debug mode" and "MCServer - release mode". The only difference between the two is which filename they use to launch MCServer - mcserver_debug(.exe) for the debug option and "mcserver(.exe)" for the release option. If you built your own MCServer executable and you built it in debug mode, you should select the debug mode option. In all other cases, including if you downloaded the already-compiled MCServer executable from the internet, you should select the release mode option.</p>
+		<p>For a first time user, it might be a bit overwhelming that there are no GUI settings in the ZBS, yet the IDE is very configurable. There are two files that you edit in order to change settings, either system-wide (all users of the computer share those settings) or user-wide (the settings are only for a specific user of the computer). Those files are regular Lua sources and you can quickly locate them and edit them from within the IDE itself, select Edit -> Preferences -> Settings: XYZ from the menu, with XYZ being either System or User.</p>
+		<p>There is a documentation on most of the settings on ZBS's webpage, have a look at <a href="http://studio.zerobrane.com/documentation.html">http://studio.zerobrane.com/documentation.html</a>, especially the Preferences section. Personally I recommend setting editor.usetabs to true and possibly adjusting the editor.tabwidth, turn off the editor.smartindent feature and for debugging the option debugger.alloweditting should be set to true unless you feel like punishing yourself.</p>
+		
+		<h2><img src="Static/zbs_logo.png" /> Project management</h2>
+		<p>ZBS works with projects, it considers all files and subfolder in a specific folder to be a project. There's no need for a special project file nor for adding individual files to the workspace, all files are added automatically. To open a MCS plugin as the project, click the triple-dot button in the Project pane, or select Project -> Project directory -> Choose... from the menu. Browse and select the MCS plugin's folder. ZBS will load all the files in the plugin's folder and you can start editting code.</p>
+		<p>Note that although ZBS allows you to work with subfolders in your plugins (and you should, especially with larger plugins), the current mcserver ZBS plugin will not be able to start debugging unless you have a file open in the editor that is at the root level of the MCS plugin's folder.</p>
+
+		<h2><img src="Static/zbs_logo.png" /> Debugging</h2>
+		<p>You are now ready to debug your code. Before doing that, though, don't forget to save your project files. If you haven't done so already, enable your plugin in the settings.ini file. If you want the program to break at a certain line, it is best to set the breakpoint before starting the program. Set the cursor on the line and hit F9 (or use menu Project -> Toggle Breakpoint) to toggle a breakpoint on that line. Finally, hit F5, or select menu Project -> Start Debugging to launch MCServer under the debugger. The MCServer window comes up and loads your plugin. If the window doesn't come up, inspect the Output pane in ZBS, there are usually two reasons for failure:<ul>
+			<li>Your code in the currently open file has a hard syntax error. These are reported as "Compilation error" in the Output pane, double-click the line to go to the error</li>
+			<li>ZBS cannot find the MCServer executable. Make sure you are editting a file two levels down the folder hierarchy from the MCS executable and that the MCS executable is named properly (mcserver[.exe] or mcserver_debug[.exe]). Also make sure you have selected the right Interpreter (menu Project -> Lua Interpreter).</li>
+		</ul></p>
+		<p>Once running, if the execution hits a breakpoint, the ZBS window will come up and a green arrow is displayed next to the breakpoint line. You can step through the code using F10 (Step Into) and Shift+F10 (Step Over). You can also use the Watch window to inspect variable values, or simply hover your mouse over a variable to display its value in the tooltip. Use the Remote console pane to execute commands directly *inside* the MCServer's plugin context.</p>
+		<p>You can also use the Project -> Break menu item to break into the debugger as soon as possible. You can also set breakpoints while the MCS plugin is running. Note that due to the way in which the debugger is implemented, MCS may execute some more Lua code before the break / breakpoint comes into effect. If MCS is not executing any Lua code in your plugin, it will not break until the plugin code kicks in again. This may result in missed breakpoints and delays before the Break command becomes effective. Therefore it's best to set breakpoints before running the program, or while the program is waiting in another breakpoint.</p>
